Hi pep's new to this and stumped with the fault that I have
As in the title, Engine Managment Light on but I have checked with snap-on diagnostic machine and Foxwell and both say the same thing no fault stored.
I recently broke the boost pressure control valve and have replaced it with a new one still the light stayed on and still no fault codes. Even if I unplug the sensor the system shows no fault.
Any help plz Oh car is a v70 mk1 2.5tdi auto
